If you shop on Amazon or use Amazon Pay, adding an extra sign-in step can significantly reduce the risk of account takeover.
This guide explains how to turn on two factor authentication for Amazon and what to expect after you enable it.
What two-factor authentication does for Amazon accounts
Two-factor authentication, often called 2FA or two-step verification, adds a second layer of protection beyond your password.
On Amazon, that usually means entering a one-time code sent to your phone or generated by an authenticator method when you sign in from a new device.
This matters because passwords alone are vulnerable to phishing, credential stuffing, and reused login leaks.
Amazon stores payment methods, delivery addresses, digital content, and purchase history, so protecting the account is important even if you only order occasionally.
Before you turn it on
Before enabling the feature, make sure you can reliably receive verification codes.
The safest setup usually includes a phone number you control and access to an email account tied to your Amazon profile.
- Confirm your mobile number is current in your Amazon account settings.
- Make sure your device can receive SMS messages or push approvals.
- Keep a recovery method available in case you change phones.
- Review any shared devices that may remain signed in.
If you use a password manager, save your Amazon password there first so you do not get locked out after changing sign-in settings.
How to turn on two factor authentication for Amazon
The exact menus may vary slightly by region or app version, but the process is similar across Amazon’s website and mobile app.
Use the account security settings to add verification for sign-in.
- Sign in to your Amazon account.
- Go to Your Account and open Login & security or Account Settings.
- Find the option for Two-Step Verification or Two-Factor Authentication.
- Select Turn on or Edit next to the security setting.
- Choose your verification method, such as SMS or an authentication app if available in your region.
- Enter the code Amazon sends to confirm the setup.
- Save backup information if Amazon offers recovery prompts or backup codes.
After activation, Amazon may ask for a code again when you log in on a new browser, sign in from a new device, or make certain account changes.
This is normal and helps verify that the person logging in is actually you.
SMS codes versus authenticator apps
Amazon commonly supports verification by text message in many markets, and some accounts or regions may also support authenticator-based sign-in options.
SMS is convenient, but an authenticator app can be stronger because it does not depend on cellular delivery.
When SMS is a good choice
- You keep your phone number stable.
- You want the simplest setup.
- You need quick access without installing another app.
When an authenticator app is better
- You want to reduce risks tied to SIM swap attacks.
- You travel frequently and may have weak cellular coverage.
- You prefer time-based one-time passwords from apps like Google Authenticator, Microsoft Authenticator, or similar tools, if supported.
Whichever method you choose, the most important factor is that you will still have access when you need it.
A security feature only helps if it is practical enough to keep enabled.
What to do if Amazon asks for a code and you cannot get it
Losing access to your verification method can happen if you replace your phone, change numbers, or restore a device.
If that occurs, start with the recovery options linked to your Amazon account.
- Check whether your old number is still active on another device.
- Look for backup codes or trusted device prompts if you saved them.
- Review whether the sign-in notification was sent to an email address you still control.
- Use Amazon’s account recovery workflow if you cannot receive codes.
If you are planning to switch numbers or phones, update your Amazon security settings before making the change.
That reduces the chance of being locked out during a login verification step.
Extra account security steps worth enabling
Turning on two-step verification is the most important move, but it works best alongside other basic security habits.
Amazon account protection is stronger when your password, device security, and sign-in settings all work together.
- Use a unique password for Amazon that you do not reuse anywhere else.
- Turn on lock-screen protection on your phone.
- Keep your email account secured with its own 2FA.
- Sign out of shared or public devices after shopping.
- Review recent orders and login activity for anything unusual.
For households where multiple people use Amazon devices, be careful about saved payment methods and voice-shopping settings.
Shared tablets, browsers, and smart speakers can create confusion if accounts are not separated clearly.
How to check whether 2FA is active
After setup, return to the same security page in your Amazon account and confirm that two-step verification shows as enabled.
You can also test it by signing out and signing back in on a browser or device you do not use often.
If Amazon prompts for a code after entering your password, the feature is working.
Keep the device you used for setup in a secure place and make sure your contact details stay current so future verification requests do not fail.
Common issues during setup
Some users run into avoidable problems when enabling account security.
Most are easy to fix once you know where to look.
- Wrong phone number: update the number in account settings before retrying.
- Delayed SMS: check signal, restart the phone, or request a new code.
- Browser issues: clear cookies or try a different browser if the settings page will not load.
- Old sessions still active: sign out of all devices if you suspect an unauthorized login.
If a code does not arrive, avoid repeated random attempts for long periods.
Instead, verify the contact method and use the account recovery path to prevent delays or temporary restrictions.
Why enabling Amazon 2FA is worth the few extra seconds
For most users, the added login step is minor compared with the protection it provides.
An attacker who knows your password still cannot easily access the account without the second factor, which is especially important if your Amazon account is linked to saved cards, Prime membership, Kindle content, or shipping addresses.
Once you know how to turn on two factor authentication for Amazon, the setup takes only a few minutes and can materially improve account safety.
Keeping your recovery options updated ensures the protection stays useful over time.
